一键清理文本或代码中重复的空格、制表符（Tab）以及多余的空白行。让您的文章结构规范，同时减少无谓的文件体积。
不会，它只会把连续重复的多个空格合并为一个正常空格。
当然可以！非常适合清除代码中的行尾空格和冗余空行。
没有限制，长篇文章或大段数据均可流畅处理。
把电子表格导出的数据发给 API，或在 Excel 中打开 API 响应，都需要在 CSV 和 JSON 之间转换。了解两种格式的差异，可以避免数据在转换中受损。
CSV(逗号分隔值)是一张表。第一行是列名，之后每一行是一条记录，值之间用逗号分隔。它是存储扁平数据(每行列都相同)最简单、最轻量的方式。
name,city,score
Kim,Seoul,92
Lee,Busan,85

{"name": "Kim", "city": "Seoul", "score": 92},

You are an experienced full-stack web developer. Build a web tool called "空白清理器" that meets the requirements below.
## Goal
Build a tool that cleans up extra spaces, blank lines and line breaks in text.
## Core features
- Trim leading and trailing spaces
- Collapse repeated spaces
- Remove blank lines
- Join lines with spaces
- Handle tabs, non-breaking spaces and full-width spaces
## Inputs
- Text to clean
- Checkboxes for each rule
## Outputs
- Cleaned text
- Number of characters removed
## Edge cases and handling rules
- Option to preserve indentation for code
- Mixed CRLF and LF line endings
- Option to remove zero-width spaces (U+200B)
- Performance on very long text
## Implementation requirements
- Build it as a single page (HTML, CSS, JavaScript) that runs entirely in the browser, and never send the user's input to a server.
- Make the UI responsive and easy to use on mobile; label every input and keep everything keyboard accessible.
- Add a Copy button for results and show clear, friendly error messages for invalid input.
- Keep the core logic in functions separate from the UI so it can be unit-tested.
## Definition of done (test cases)
- ' a b ' becomes 'a b'
- Removing blank lines leaves none
- Non-breaking spaces become normal spaces
First outline your implementation plan in at most five lines, then write the complete code, and finally explain how to check the test cases above.在 Claude Code 等 AI 编程助手中保存为 .claude/skills/build-whitespace-remover/SKILL.md，以后开发或修改此工具时可重复使用。

# Build: 空白清理器
## Goal
Build a tool that cleans up extra spaces, blank lines and line breaks in text.
## Workflow
1. Review the required features, inputs and outputs below and ask about anything missing first.
2. Implement the core logic as pure functions separate from the UI.
3. Check the logic against the test cases in the verification list.
4. Build a responsive UI with an input form, a result area and a Copy button.
5. Reproduce each edge case listed under Rules and refine the error messages.
## Core features
- Trim leading and trailing spaces
- Collapse repeated spaces
- Remove blank lines
- Join lines with spaces
- Handle tabs, non-breaking spaces and full-width spaces
## Inputs
- Text to clean
- Checkboxes for each rule
## Outputs
- Cleaned text
- Number of characters removed
## Rules
- Option to preserve indentation for code
- Mixed CRLF and LF line endings
- Option to remove zero-width spaces (U+200B)
- Performance on very long text
- Build it as a single page (HTML, CSS, JavaScript) that runs entirely in the browser, and never send the user's input to a server.
## Verification
- [ ] ' a b ' becomes 'a b'
- [ ] Removing blank lines leaves none
- [ ] Non-breaking spaces become normal spaces
